Micro trains

The world's smallest working model train set has been unveiled ­ measuring just 1/8th of an inch by 1/4 of an inch. At 1-35200 scale to the real thing, the five-carriage train travels around an oval route including ride through a tunnel. Created by New Jersey model train enthusiast David Smith, the model was built using nothing more fancy than a craft knife and a steady hand. It is powered by a standard two inch rotating motor head and carved out of mouldable plastic.

Crash-test baby

A 6-month-old baby had a miracle escape after his pram rolled onto the tracks and into the path of an oncoming train at a railway station in Melbourne. Security video footage released on Friday shows the baby's mother looking away for a moment as the pram suddenly rolls off the edge of a station platform and onto the tracks at Ashburton station. The mother looks back and panics as she watches the oncoming train hit the pram, dragging it about 130 feet along the track as the desperate driver tried to stop the train. Miraculously, the baby boy survived with only minor injuries, including a bump to his head.
